ROSE MECHANISM OPTIONS

BEARING: Stainless steel roses with sealed ball bearings, for optimum performance. The bearing rose to bring smooth, positive and flawless operation while addressing all the common door knob issues. The unique bearing rose is our preferred option to be used with all door knobs.

BASIC: Flat aluminium rose, that may have to be used in some situations where the Grip Tight, Self-centring, Sprung Bearing Inner-Rose System cannot be accommodated, for example, thin metal doors. This rose option is not our preferred rose to supply with lever handles or door knobs, it does not offer any of the properties and or performance of the grip tight or sprung rose designs, and operation of the handles are purely down to the strength of the lock and highly accurate installation.

FIXED: Stainless steel roses with TIG-welded fixed spindles. A highly durable fixed rose for use where a lever handle or door knob is not required to turn, or rotate but is needed to be installed in a push/pull application, e.g. when used in conjunction with a magnetic catch on a cupboard door.

HSTO BEARING: Stainless steel single sided rose with TIG welded spindle with bearing for smooth operation, designed for door knobs. The bearing rose brings smooth, positive and flawless operation while addressing all the common door knob issues. To be operated from one side of the door by the use of a single door knob.
